Jiaxing City Qunbang Hardware Co., Ltd. (brand: QBH) is a fastener enterprise integrating production, design, sales, and after-sales service. The company is located in the Hangzhou-Jiaxing-Huzhou Plain, close to Shanghai, Ningbo, and Zhapu ports. Thanks to its superior geographical position and convenient transportation, the company has natural advantages for export business.
The company mainly produces high-strength fasteners, with bolts and nuts as its core products. The main standards include DIN, ANSI/ASME, JIS, UNI, ISO, AS, BS, GB, and others. Our products are widely used in bridges, roads, petroleum pipeline facilities, wind power generation, and steel structure projects. Carbon steel bolts are available in grades 4.8, 5.8, 6.8, 8.8, 10.9, and 12.9; nuts in grades 4, 6, 8, and 10. Stainless steel fasteners are mainly made of 201, 304, and 316. Since its establishment, QBH has undergone over ten years of development. We are equipped with comprehensive testing equipment and maintain good cooperation with SGS and TUV. Each batch of products is accompanied by a 3.1 or 3.2 certificate, further ensuring quality.
In 2017, we registered the trademark “QBH” in China, the EU, and the United States, and obtained six fastener product patents. We have also been awarded the Zhejiang Province Science and Technology Small and Medium-sized Enterprise certificate and the ISO9001:2000 certificate. As the company continues to grow and customers demand more diversified products, we have further strengthened our manufacturing capabilities.
In 2025, QBH officially expanded with two new factories:
China Factory (Ningbo): NINGBO QB FASTENER MANUFACTURING CO., LTD. Add: No.100, Tianshen Road, Jiulonghu, Zhenhai, Ningbo City, Zhejiang Province, China
Vietnam Factory: Công ty TNHH Sản xuất và Thương mại Khải Tín Huy Add: Street No.1, Thuan Dao Expanded Industrial Park, Long Dinh Ward, Can Duoc District, Long An, Vietnam
With the addition of these new facilities, QBH has significantly increased production capacity, optimized cost structures, and enhanced supply chain flexibility. Starting from 2015, QBH had already begun cooperating with several fastener enterprises to enrich product variety and improve pricing. Now, with our own manufacturing bases in both China (Ningbo) and Vietnam, we can offer even more competitive prices, shorter lead times, and better quality control across a wider range of products.
QBH has always been committed to providing customers with efficient, convenient services and high-quality products. Our mission is to create a pleasant trading experience for our customers, deeply participate in their construction projects, and make progress together.
